2 Claims.

This invention relates to improvements in elevated tanks and more especially anelevated steel tank as is commonly employed for the storage of water and other fluids.

Among the features of my invention is the provision of a substantially spherical tank supported on a substantially cylindrical riser pipe which in turn is supported by radial hollow tubular legs.

Other features and advantages of my invention will appear more fully as I proceed with my specication.

In those forms of device embodying the features of my invention shown in the accompanying drawings, Fig. 1 is a view in side elevation partly in section, Fig. 2 is an enlarged sectional l View of the upper portion, Fig. 3 is a horizontal sectional View looking downwardly, Fig. 4 is a vertical sectional view showing a modified form of bottom, Fig. 5 is a top plan View of the modied bottom, and Fig. 6 is a view similar to Fig. 4 l

showing another modification.

As shown in the drawings the tank includes a substantially spherical portion Ill supported on a substantially cylindrical riser pipe I by means of an inverted frusta-conical collar portion I2 which joins the spherical portion tangentially. The junction line between the spherical portion Ii] and the collar I2 is indicated in Fig. 2 by the constructional broken line I3 which may or may not indicate the junction line between plates. In

this figure the broken line I4 is also constructional for the purpose of showing an imaginary continuation of the spherical portion ID to illustrate better the tangential connection with the upper portion of the collar I2 and the spherical portion Ill.

Structures of this kind are ordinarily built of sheet metal plates of various shapes and sizes suitably Welded together, and no attempt; has beenmade to show the separate plates or their junction lines.

The particular feature in this application is the method of supporting the structure. In general this is accomplished by the provision of radial tubular legs here shown as three in number although there may be more.

In the form shown in Figs. 1 and 3 the legs, as indicated by I5, are slanted substantially at an angle of 45. These'legs are hollow and one of them as indicated by I5a may be lled with water I6 and Serve to connect the inlet I1 with the bottom of the riser pipe I I, the latter being provided with a suitable opening IIa to permit the passage of water therethrough.

The lower ends of the legs I5 are supported upon suitable foundations I8. I9 indicates tierods that may be used to connect the legs to give additional support.

In the construction shown in Figs. 4 and 5 the radial legs I I5 are horizontal and one of them as indicated by H5EL is filled with water I6 to connect the inlet pipe I I I with the bottom of the riser pipe I I I, a suitable hole I I la being provided for this purpose. In the construction here shown, the lower end of the riser pipe I|| is joined to a spherical bottom |20 resting on a foundation IIB. The outer ends of the legs |I5 are also supported upon foundations ||8a. This support is accomplished by closing the ends of the legs with vertical plates I2 I, the lower edges of which are carried on the plates |22 resting on the foundations IISa. A hole |20a in the upper portion of the spherical part |26 permits passage of Water therefrom into the riser pipe II I.

The construction shown in Fig. 6 is similar to that shown in Figs. 4 and 5 except that the entire Weight is taken by the ends of the legs 2I5 on the foundations 2|8, there being no foundation under the spherical bottom portion 220.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications..

Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in view of the prior art.

What I claim as new, and desire to'secure by Letters Patent, is:

1. An elevated tank, including: a substantially cylindrical riser pipe; a hollow substantially spherical portion of substantially larger diameter than the riser pipe supported on the upper endr of the riser pipe and in communication therewith; a hollow substantially spherical portion at the lower end of the riser pipe and in communication therewith; and a plurality of radial hollow tapering members with their larger ends attached to said last-mentioned spherical portion and serving as supporting legs for the tank.

2. A device as claimed in claim 1, with an inlet pipe entering one of the legs, said leg serving as a fluid connection between said inlet pipe and said riser pipe.
